The Ecofont uses up to 20% less ink

The Ecofont is a new Dutch sans-serif font with holes that uses up to 20% less ink. Based on Verdana, it's free to download and use. The results vary but the Ecofont works best when using font size 9 or 10, which has the look of draft quality.

The Ecofont is developed by SPRANQ, based on a hunch of Colin Willems, which ideas for other savings:

• End-users: print only when necessary, use a modern, efficient printer and use unbleached paper.
• Graphic designers: use modern color separation techniques to avoid unnecessary wastage in ink. In paper choice, take the environment into account.
• (Offset) printers: avoid modern laser techniques that make ink indivisible from the paper. Keep an eye on innovations, such as plant-based ink.
• Printer manufacturers: invest in environment-conscious innovation.
